During single clock inflation, hidden fields (i.e. fields coupled to the inflaton only gravitationally) in their adiabatic vacua can ordinarily only affect observables through virtual effects....

Given a graph G and a bijection f : E(G)\rightarrow \{1, 2, \ldots,e(G)\}, we say that a trail/path in G is f-\emph{increasing} if the labels of consecutive edges of this trail/path form an...

For a compact Poisson-Lie group K, the homogeneous space K/T carries a family of symplectic forms\omega_\xi^s, where \xi \in \mathfrak{t}^*_+ is in the positive Weyl chamber and s \in \mathbb{R...

We test various conjectures about quantum gravity for six-dimensional string compactifications in the framework of F-theory. Starting with a gauge theory coupled to gravity, we analyze the limit...

We discuss walking behavior in gauge theories and weak first-order phase transitions in statistical physics. Despite appearing in very different systems (QCD below the conformal window, the...

We construct a formal global quantization of the Poisson Sigma Model in the BV-BFV formalism using the perturbative quantization of AKSZ theories on manifolds with boundary and analyze the...

We define a generalization of the winding number of a piecewise C^{1} cycle in the complex plane which has a geometric meaning also for points which lie on the cycle. The computation of...

The truncated two-point function of the ferromagnetic Ising model on \mathbb Z^d d\ge3 in its pure phases is proven to decay exponentially fast throughout the ordered regime (\beta>\beta_c...

We describe a framework to construct a perturbative quantization of nonlinear AKSZ Sigma Models on manifolds with and without boundary, and show that it captures the change of the quantum state...

The universal enveloping algebra of {\cal W}_{1+\infty} is isomorphic to the affine Yangian of \mathfrak{gl}_1. We study the N=2 supersymmetric version of this correspondence, and identify the...

The geometric optics approximation traditionally used to study the propagation of gravitational waves on a curved background, breaks down in the vicinity of compact and extended astrophysical...

In this note we discuss vacant set level set percolation on a transient weighted graph. It interpolates between the percolation of the vacant set of random interlacements and the level set...
